What is it about?
The paper describes how to reduce the molar mass and molar mass dispersity of polypropylene through chain-scissioning (also known as vis-breaking) by reactive extrusion with aqueous hydrogen peroxide as the only reagent and water as the only by-product

Why is it important?
The process produces no organic volatile relative to the current industrial process which makes use of organic peroxides. Ther can also be significant cost savings.
